Definitions
- the present invention relates to a stirring device comprising a propeller shaft driven by a drive means, the propeller shaft being guided relative to a body by means of a bearing, the device agitating further comprising a seal integral with the body and in contact with the patella so as to seal with the fluid to be agitated.
- agitators commonly called side entrances
- This system is based on a pivot for the mechanical guidance and a partially spherical shaped part serving as a support for a semi-static seal.
- a seal between the static part of the machine and the sphere is generally used.
- This seal is a wear part that must be changed in a period of 1 to 5 years, preferably every 2 years.
- the orientation system is essential to allow the agitation of large tanks and interest the entire volume with a minimum power consumption.
- the volume of the tank can reach 200 000 m 3 , emptying the tank during a maintenance or maintenance operation is, especially in case of leakage, very complex because this operation lasts several hours and can reach several days to very large tanks.
- Mixed substances are generally dangerous and polluting which makes their possible transfer to a backup tank unthinkable as technically because an additional tank of the same capacity is not necessarily available, that ecological given the risk of leakage of the product during the transfer.
- the ball may be adapted to adopt two positions, a first operating position where the seal is in contact with the ball joint and a second maintenance position where the contact zone is in contact with the ball joint.
- the seal support may comprise a proximal end in the vicinity of the fluid to be sealed ending in a shoulder and a contact zone.
- the seal body may include an orifice for checking the static seal.
- Fig. 1 is a general view in longitudinal section of a device according to the invention
- Fig. 2 is a longitudinal sectional view, on a larger scale, of a sealing device according to the invention, in the operating position, and
- Fig. 3 is a longitudinal sectional view, on a larger scale, of a sealing device according to the invention, in the maintenance position.
- FIG. 1 a general view of the various elements of the device according to the invention.
- Device D comprises a propeller shaft 1 mounted on a bearing 2 by means of bearings.
- the propeller shaft 1 has a first end 1a located in contact with a fluid to be stirred contained in a tank R and on which is mounted a propeller 3.
- the propeller shaft 1 also has a second end 1b on which is mounted a pulley 4 for driving the propeller shaft 1 via a motor 5 and a belt 6.
- a ball 7 in sliding connection on the shaft 1.
- the transmission of torque between the shaft 1 and the ball 7 is provided by splines or a key-type device.
- a sealing device of the lip seal type is mounted in a support 9 secured to the reservoir R and in contact with the ball 7 so as to seal the reservoir R.
- the support 9 comprises a cylindrical housing 9a in which is mounted the lip seal 8.
- the cylindrical housing 9a has a distal end opposite the fluid to be sealed having an opening 9b for the insertion and extraction of the gasket 8.
- the cylindrical housing also presents a proximal end in the vicinity of the fluid to be sealed having a shoulder 9c on which the gasket 8 abuts.
- the shoulder 9c terminates in a contact zone 10 of substantially frustoconical shape.
- the support 9 is held in place by holding screws. Extraction screws allow the translation of the support 9 and its extraction.
- the static sealing system according to the invention consists in moving the seal relative to its operating position. This displacement is obtained either by axially moving the joint support with it relative to the sphere, or by moving the sphere relative to the joint.
- Intervention time less than 5 minutes, usually about 3 minutes.
- Intervention time less than 15 minutes, and usually about 7 minutes.
- the total time of this operation is on average 35 minutes and does not exceed 50 minutes.
- the maintenance time is very reduced.
- the emptying of the tank is not necessary whereas it may require several days in the case of large tanks.
- the device according to the invention required the development of new solutions but allows many advantages.
- the device according to the invention is easy to set up and that the size is maintained compared to existing devices.
- the objective of allowing a replacement of the full tank seal is achieved and in addition an ability to verify the safety of the system before disassembly has been achieved.
- this technical solution is not too limiting in terms of choice of materials which allows a better product / process compatibility.
- the piece 7 may also have another shape, in particular ovoid.
